Abstract:
A system may receive, from a user device, a request to receive content via a first base station, where the content was previously being received, as multicast content, via a second base station; determine, in response to the request, whether the first base station can process multicast content; transmit a copy of the content, to the user device via the first base station, as multicast content, based on a determination that the first base station can process multicast content; and transmit the content, to the user device via the first base station, as unicast content, based on a determination that the first base station cannot process multicast content.
